Power Requirements
Use the following guidelines to ensure your site is equipped with enough
power to support the system. All circuits must be 50 or 60 Hz ± 2 Hz,
single-phase with < 6% total harmonic distortion. See
additional power requirements.
♦
Circuit 1:
ISQ EC or ISQ EM MS plus the foreline pump
. 100-
240 Vac, 15 A
MAX
. The foreline pump must be set to the line
voltage used.
♦
Circuit 2:
LC or IC and computer
. See manuals for power
requirements for the specific system. Each module (e.g.
pump, autosampler, column compartment, detector)
needs its own plug on circuit 2.
♦
Additional circuits may be needed for other
equipment.

Table 3: Power requirements
The power quality supplied to your system is very important. It must be
stable and within the minimum specifications listed in this section.

Test the power source quality in your laboratory to offset line
voltage problems. Improving power source quality is a complex

Foreline pump plugs into the ISQ EC or ISQ EM MS. At startup, the foreline pump draws an additional 21.5 A at 120 V and an additional 20 A at
230 V.
